You'd like Interlingua then:
Iste non es le problema maxime. Le problema major es que paucos homines parla Esperanto. Io non lo usa desde longe tempore.
(caveat: I do not speak Interlingua at all. This is just what I managed to put together from a grammar handbook and a dictionary)
Had Zamenhof created his language to be more like Interlingua, we might be using this in international communication by today. Compared with Esperanto, it's easier for Romance speakers, but adequately more difficult for the others.
I just read this in the Wikipedia article on the Mattaponi River and it really tickled me. If only all language were so rational!
